'''3-Methylthiophene''' is an [organosulfur compound](/source/organosulfur_compound) with the formula CH<sub>3</sub>C<sub>4</sub>H<sub>3</sub>S.  It is a colorless, flammable liquid.  It can be produced by sulfidation of [2-methylsuccinate](/source/2-Methylsuccinic_acid).<ref>{{cite journal|title=3-Methylthiophene|author1=R. F. Feldkamp |author2=B. F. Tullar|journal=Org. Synth.|year=1954|volume=34|page=73|doi=10.15227/orgsyn.034.0073}}</ref> Like its isomer [2-methylthiophene](/source/2-Methylthiophene), its commercial synthesis involvess vapor-phase dehydrogenation of suitable precursors.  3-Methylthiophene is a precursor to the drug [thenyldiamine](/source/thenyldiamine) and the pesticide [morantel](/source/morantel).<ref name="Ullmann">{{cite book| first = Jonathan | last = Swanston |chapter = Thiophene | title = Ullmann's Encyclopedia of Industrial Chemistry | publisher = Wiley-VCH | location = Weinheim | date = 2006 | doi = 10.1002/14356007.a26_793.pub2| isbn = 3527306730 }}.</ref>
